Adding additional SFPs
Learn how to add additional SFPs to the storage enclosure.
Before you begin
Note: You must have the correct type and speed of small form-factor pluggable
(SFP) transceivers. Using the wrong SFP transceiver might result in loss of data
access.
Be careful when you are replacing the hardware components that are located in the
back of the system that you do not inadvertently disturb or remove any cables that
you are not instructed to remove.
Ensure that you are aware of the procedures for handling static-sensitive devices.
About this task
To install additional SFP transceivers, complete the following steps:
Procedure
1. Read the safety precautions in the IBM Systems Safety Notices . These guidelines
help you safely work with the system.
2.
Shut down all host I/O to the enclosure.
3. To install a new SFP transceiver, complete the following steps.
a.
If used, open the release handle on the SFP transceiver.
b. Push the new SFP transceiver into the aperture in the interface card until it
stops.
c. If the SFP transceiver uses a release handle, close the handle to secure the
SFP.
d. Gently pull the SFP transceiver. If it is installed correctly, it does not move
from its aperture.
4. Repeat step 3 as necessary to install the remaining SFP transceivers.
5. Connect Fibre Channel cables to the new SFP transceivers.
6. To reset the interface cards where you installed the new SFP transceivers, enter
the
